and improved bearing of that character adapted especially for use upon steam and electric railway cars, although useful for various other purposes.

It is the object of the invention to provide a journal bearing having novel means for taking care of the end thrust at the end of the axle or journal.

Another object of the invention is to providc a journal bearing having the improvements above noted, and which at the same time, is comparatively simple compact and and durable and efficient in use. 1

With the foregoing and other objeets in view which will appear as the description proceeds, the invention resides in the eombi-- nation and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. The invention is illustrated in the accompanying drawing, wherein Figure 1 is a diametrical section of, the bearing, portions being shown in elevation.

Fig. 2 is a cross section taken on the line 2-201? Fig. 1.

In the drawing, there is illustrated an axle 1 having secured thereon the wheel 2' and provided at the outside of. said wheel with the usual journal 3 projecting within a suitable journal box the journal box is provided with a groove 5 in which a packing ring 6 is seated to bear against the wheel.2 and exclude dust, grit and other extraneous matter from the bearing, and to retain oil therein. The journal box 4 is provided with a bore 7 extending from end to end, and. is further provided with a counter bore 8 at the outer end of the bore 7 providing an outwardly facing shoulder 8. A hearing shell or sleeve 9 is slipped longitudinally within the bore 7, and 18 pro- 4. The inner end of vided .ut its outer end with an outturned flange 10 of non-circular outline, as seen in- Fig. 2, that portion of the counter bore 8 ad acent to the shoulder 8 being of similar outline to snugly receive the flange l0 and prevent the shell 9 from turning. The flange 10 seats against the shoulder 8. lwo sets of bearing rollers 11 are disposed between the journal 3 and shell 9, their ends being reduced and engaged with rings 12, whereby to hold the rollers in proper operative posltion. I

An end thrust member or cup 13 is disposed within the counter bore 8 with its cess facing the end of the journal, and the rim of the-cup 13 is provided with an out turned flange 14. of, the same outline as the flange 10, whereby to prevent-the cup 13 from turning within the journal box i, the flange 14L seating against the flange 10, as seen in Fig. 1. A retaining ring 15 is threaded within the counter bore 8 and fits rotatably upon the cup 13, said ring hearing against the flange let to clamp the flanges 10 and 14 between the shoulder 8 and retaining ring 15, thereby holding the shellS) and cup 13 in place firmly. The ring outstanding lugs 15 can be provided with for applying and 160i other suitable means removing it.

The end of. the axle or its journal is reduced to provik a stud 17 within the cup 13, there beingnfillet between the sides of the stud and the shoulder formed by the stud,- which provides an. annular ball race 18. The inner corner of the cup i lias a fillet providing an annular hall race 19 nonfronting-the ball race 18, and .an annular series of anti-frictional balls 20 disposed between the ball races 18 and 19 and between the shoulder of the journal 3 and the central portion of the cap 132 The rollers strain, while the balls 50 will talre up the end thrust, it being understood that one of the thrust bearings'is used for each end of the axle. The cup 13 not only provides a ball cup, but also provides a cap closing the outer end of the journal box 4.

Having thus described the invention, what is claimed as new is:-

1. A bearingembodying a journal box, a journal rejecting into it, a ring engaged removab y within the jdu rnal box, a ball cup fitted within and held by said ring and having a portion bearing against the inner 1%..will take up the lateral 'latented May 2%, Mitt? duced end providing a portion of the ring to hold the cup in place, and anti-frictional balls between said journal and the interior of the cup.

A bearing embodying a journal box, a journal projecting into it having a reduced end providing a shoulder, a ring engaged removably within the journal box, a ball cup titted snugly within said ring and having an outturned flange at its edge seated against the inner side of said ring to hold the cup in place, and anti-frictional balls between said shoulder and cup within said cup.

3. A bearing embodying a journal box, a journal projecting into it and having a reshoulder, a ball cup within the journal box having an outturned flange of non-circular outline fitted within the journal box to prevent rotation of said cup therein, anti-frictional balls between said shoulder and cup around said reduced end, and a ring surrounding said cup, bearin; against the fiange thereof and engaged removably within the journal box.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
